稻瘟病是我国水稻作物三大病害之一,特别是穗颈稻瘟危害水稻的穗部,产量损失严重,常年达两成以上,对我国平原湖区、丘陵及中山地区的水稻生产是很大的威胁。湖北省沙市农药厂成功地研制出杀菌剂克瘟唑,在小试鉴定合格,经湖北省科委和教育厅批准通过后正式投产。为了验证克瘟唑防治稻瘟病的实效,并与国内、外同类农药产品作比较,沙市农药厂和宜昌县植保站联合进行大田药效试验,试验结果表明,对水稻穗颈稻瘟病的防效优于日本产三环唑和上海产克瘟灵。
Rice blast is one of the three major diseases of rice crop in our country. Especially rice panicle disease endangers the ear of rice. The yield loss is serious, reaching more than 20% of the annual, which is very great for the rice production in the plain lake area, hilly area and Zhongshan area of our country Threats.
